In 2374, the briefly deposed Grand NagusZek invited Nilva to Deep Space 9 to meet with Ishka, who planned to convince him of the lucrative opportunity that allowing Ferengi females to spend and buy would mean to the economy, especially Slug-o-Cola, which was experiencing fierce competition from Eelwasser. After Ishka had a heart attack and was incapacitated, Quark was surgically altered to appear female, known as Lumba. Nilva was convinced that Quark was female and agreed to support Zek's return and the establishment of the female right to make profit. (DS9episode: "Profit and Lace")
